Replying to Psycology project ideas

My teacher told us that for out final project we can choose any topic that we want to in psychology (he really does mean ANY topic) and basically either do a shitload of research or conduct a small scale study and create a 10min presentation.

The real problem is that it's not a really specific project, which is nice, but it makes it really hard to come up with ideas.

any suggestions would be really nice, i just cant come up with anything good, most of the "interesting" disorders are taken and I don't really want to just do a plain research paper, I already did one for World Lit. this year and once is definitely enough.
